title = "Polarization dependent photoemission as a probe of the magnetic ground state in the van der Waals ferromagnet VI3",
abstract = "Van der Waals ferromagnets are thrilling materials from both a fundamental and technological point of view. VI3 is an interesting example, with a complex magnetism that differentiates it from the first reported Cr based layered ferromagnets. Here, we show in an indirect way through angle resolved photoemission spectroscopy experiments, the importance of spin-orbit coupling setting the electronic properties of this material. Our light polarized photoemission measurements point to a ground state with a half-filled e ± ′ doublet, where a gap opening is triggered by spin-orbit coupling enhanced by electronic correlations.",

We would like to acknowledge invaluable advice from Jonathan Denlinger from the Advanced Light Source at LBL as well as important discussions with Peng Zhang and calculations from Elton J. G. Santos, Benjamin Carpenter and Ignacio Martin Alliati. While this manuscript was under review, we became aware of a similar ARPES work that reports the VI surface to be stabilized by filled a states and a splitting between the a and e′ levels, similar to the results reported here (Ref. ). 3 1g 1g g Publisher Copyright: {\textcopyright} 2022 Author(s).",
